Definitions
- the invention relates to a motorized functional unit for installing toilets and to a toilet installation comprising such a unit.
- the output shaft rotates and simultaneously drives the pump and the turbine.
- the rinsing water is sucked and discharged into the toilet bowl while the turbine macerator sucks at the same time the contents of the toilet bowl.
- the flushing rate must be high enough to allow simultaneous suction by the blower turbine.
- the functional unit according to the invention thus provides two functions (on the one hand, water filling with the pump in a first direction of rotation and, on the other hand, pumping and splitting waste with the turbine in a second direction opposite rotation) which are dissociated unlike the prior art where the two functions are performed simultaneously.
- the turbine The macerator is configured to ensure in one direction of rotation (second direction of rotation of the motor) both the pumping or suction of waste water and waste and the mislaying of this waste.
- the macerator turbine thus comprises for example peripheral members mounted on a central hub and these organs ensure both the pumping or suction of waste water and waste and the mislaying of this waste (in the second direction of rotation of the engine). .
- This arrangement is particularly simple and effective with respect to an arrangement wherein pumping and tearing are performed by separate members and spaced apart from each other. Furthermore, each function is performed using a different direction of rotation of the motor so that only one function is performed at a time for a given direction of rotation. The noise associated with the operation of such a functional unit is thus considerably reduced. More particularly, the self-priming pump and the macerator turbine each have a preferred direction of rotation (opposite to each other) in which they are each active, that is, they produce their full effect. or maximum effect in this direction of rotation. By cons, in the case where each of them is rotated in the opposite direction to its preferred direction of rotation called "active", it does not produce its full effect in the functional unit.
- the turbine blade rotating in the first direction of rotation can not or almost not suck water and can not or almost not tear waste.
- Such a functional unit in which the macerator turbine would rotate in the first direction of rotation would therefore not satisfactorily ensure the function of suction of waste water and waste and of dilaceration of said waste.
- the waste would be imperfectly dilacerated, even undamaged, and this could lead to malfunctions such as clogging of lines.
- the decoupling of the two functions makes it possible to optimize the operation of such a functional unit and, in particular, the installation of toilets that can integrate it. Indeed, the filling of the bowl is first performed (first direction of rotation of the motor), then the pumping and the dilaceration of solid waste mixed with the filling water occurs (second direction of rotation of the engine).
- the blade mill comprising blade blades which are configured for, in the second direction of rotation of the motor, to draw the waste water and the solid waste by its entry and to dilacerate the waste aspired
- the turbine has a diameter which is at least equal to the internal diameter of the connection between the inlet of the turbine and the evacuation of the bowl, the diameter being that of a circle which tangents the outer peripheral edge of the blades; such an arrangement allows the waste to be dilactively satisfactory without clogging; if the diameter is too small, the risk of clogging of the turbine by aspired waste is indeed high and there is the formation of too many swirls disruptive; if the diameter is too large, the waste is not sufficiently dilacerated because the flow velocity is too low.
- the invention provides for the use of the motorized functional toilet unit as briefly described above or the toilet facility as briefly described above onboard a maritime machine.
- the functional unit or the installation of toilets according to the invention can be used for other purposes and / or in other technical fields than on board marine vehicles such as ships and -marins.
- This method provides the same advantages of time separation of the main functions of the toilet functional unit according to the invention as briefly described above.
- the output of the self-priming pump is blocked in order to prevent it from sucking by said outlet.
- the self-priming pump 24 is a pump with deformable blades as illustrated on FIG. figure 2 .
- the control member of the motor 30 is for example a switch with three positions or control states and one of whose positions corresponds to a stopping position of the motor.
- This pump 24 comprises a housing to which are connected an inlet 24a and a water outlet 24b (and pipes or pipe portions for connection to the source 26 and the bowl 14 respectively) and in which is arranged a chamber 24c.
- the pump 24 comprises, housed in the chamber 24c, a central hub 24d at the periphery of which are regularly distributed several deformable blades 24e.
- Chamber 24c presents on a part 24g its circumference an oblong shape and, on the diametrically opposite portion 24, a circular shape.
- the turbine (hub 24d and 24e blades) is mounted in the chamber 24c so that, during the rotation of the turbine, the blades 24e crash against the zone 24g of the inner peripheral wall of the chamber which is closest to the blades, thereby sucking a volume of water from the inlet 24a between the blades and evacuate through the outlet 24b.
- the blades which are in contact with the diametrically opposite zone 24 of circular shape of the wall are relatively weakly curved insofar as the required lifting height is relatively low and where it is sought to reduce the friction and the wear of the blades. against the wall.
- the blades are made of 60 shore nitrile rubber to impart flexibility and self-lubrication properties.
- the oblong shape of the zone 24g is not very pronounced in order to minimize the noise generation and to allow both directions of rotation of the pump turbine.
- the pump 24 is equipped at its outlet 24b (outlet of the chamber 24c) of a nonreturn valve system 24f which is shown, for example, by a ball and a valve seat.
- An exemplary macerator turbine 28 is illustrated on the figure 3 .
- the turbine comprises a turbine wheel 32 which comprises a central portion 34 and an annular portion 36 carrying at its periphery a plurality of blade blades 38.
- the blades comprise ridges which are sharpened so as to be able to tear the solid waste (the edges are more particularly arranged opposite the inlet 28a of the turbine).
- Each blade is folded relative to the circumference of the annular portion and extends for example at an angle of the order of 45 ° relative to the latter. More particularly, each blade is curved and has a generally helical shape.
- the central portion 34 comprises a cylindrical end 34a open at its free end and surrounded by a flange 34b also cylindrical.
- the turbine wheel 32 is mounted in the central chamber 40 of a housing 42 which is open on a face constituting the l inlet 28a of the turbine. This open face of the case is arranged opposite the open end of the duct portion 29 (connection between the evacuation 16 of the bowl and the inlet 28a) of the figure 1a when the turbine is installed against it.
- the blade blades 38 of the turbine are configured to draw the waste water and solid waste through its inlet 28a when the motor rotates in the second direction of rotation and to dislodge the waste in the same direction of rotation.
- This dual function is provided by the single turbine which forms a single piece, contrary to the arrangement described in the document US 6,085,364 where the macerating members are knives rotatably mounted on a shaft and which are axially distant from the turbine for pumping only.
- the compactness of the arrangement of the macerator turbine 28 makes it possible to avoid the problems related to the mechanical balancing of a longer motor shaft in the document US 6,085,364 .
- the outlet of the turbine is hydraulically configured to, on the one hand, promote the evacuation of wastewater and waste garbage when the turbine wheel rotates in the direction indicated by the arrow on the figure 3 (This direction corresponds to the second direction of rotation of the motor) and, on the other hand, make it difficult to draw water through this outlet when the motor rotates in the first direction of rotation.
- the outlet of the turbine takes the form of an extension of the housing 42 which is disposed adjacent to the central chamber 40 in the form of an outlet duct 42a.
- the outlet duct 42a extends outwardly from the housing first tangentially to the outlet of the chamber, then changing direction relative to the tangential direction of exit of the chamber so as to close the angle relative to this direction towards the housing (the duct is curved).
- the outlet duct wraps around the casing in a way, thus conferring on the assembly a general shape of snail shell (thus obtaining a compact and therefore compact assembly).
- the change of direction (here of 90 °) between the tangential direction of exit of the chamber and the perpendicular to the outlet orifice 28b is such that water can hardly be sucked by the outlet orifice under the effect of the rotation of the blades in the first direction of rotation of the engine.
- the length of the conduit 42a is such that the chamber is not visible from the outlet port 28b. However, this length may vary according to need and, for example, wrap more around the case.
- the motor 22, the self-priming pump 24 and the macerator turbine 28 of the motorized functional unit 20 are arranged in a rectilinear configuration according to the alignment of the output shaft 22a of the motor.
- the pump 24 is surrounded by the motor 22 and the turbine 28.
- the inlet 28a of the turbine is thus directly connected to the duct portion 29.
- the diameter of the turbine provided with its blades is at least equal to the internal diameter of the portion of conduit 29. This allows the turbine to satisfactorily perform the dual function (pumping and grinding) avoiding the clogging problems inherent in the arrangement described in the document. US 6,085,364 (winding hair, debris, dirt, ... around the knives and the tree on which they are mounted). Indeed, the function of disintegration occurs at the blades 38 at the periphery of the flange 36 of the turbine and not, as in the prior art, on knives carried by a shaft of a relatively small diameter. In practice, the diameter of the turbine is between 8 and 12 cm and is for example equal to 10 cm.
- FIG. figure 1b A variant of the installation 10 is shown in FIG. figure 1b .
- the installation 50 includes the same elements as those of the figure 1a , with the exception of the motor 52 (the same references as on the figure 1a are kept for the elements unchanged).
- the motor 52 is disposed between the turbine 28 and the pump 24.
- the output shaft of the engine opens on both sides of the carcass of said engine by its two opposite ends 52a, 52b and the turbine 28 and the pump 24 are each mounted on one of the two open ends (end of axis). This arrangement makes it possible to balance the structure of the functional unit (variant of the functional unit 20 of the figure 1a ) and facilitates maintenance.
- FIGS. 4 and 5 illustrate the two possible modes of operation of the installation of Figures 1a and 1 b.
- the user actuates the control member 30 to control the operation of the motor in the first direction of rotation (this direction is shown schematically on the output shaft 22a of the motor which has been deported to the right of the Figures 4 and 5 for the sake of clarity).
- the user thus actuates the switch in a first position (first control state) which closes an electrical circuit 50 in order to send an electric current into the coils of the DC motor in a first direction.
- the rotation of the output shaft 22a in the first direction causes the rotation of the pump turbine 24 in the direction of the arrow on the figure 2 .
- This rotation of the turbine creates a suction, through the inlet 24a, the filling water from the source 26 and a discharge, through the outlet 24b, the water sucked, thus bringing the water into the bowl 12 to fill and rinse it (see the direction of water flow indicated by the arrows).
- the pump 24 is activated and then plays its full role without being disturbed by a parallel and opposing operation of the macerator turbine 28.
- the wheel 32 of the macerator turbine is rotated in the opposite direction of the arrow on the figure 3 . Given the configuration and the orientation of the blade blades, their rotation in this direction has no effect on the volume disposed upstream, namely the portion of conduit 29 and the bowl 12.
- the user actuates the control member 30 to control the operation of the motor in the second direction of rotation
- the user thus actuates the switch in a second position (Second control state) which closes an electrical circuit 50 to send an electric current into the DC motor windings in a second direction.
- the rotation of the output shaft 22a in the second direction causes the rotation of the impeller turbine wheel 32 in the direction of the arrow on the figure 3 .
- This rotation of the turbine wheel 32 creates a suction, through its inlet 28a connected to the outlet 16 of the bowl 12, the waste water and solid waste (faeces ...) from the bowl which had been previously filled with water (first mode of operation).
- the solid waste is dilacerated / milled by the blade blades 38 of the turbine turbine and the waste water and waste dilacerated caused by the rotation of the turbine are then discharged through the outlet conduit 42a and the outlet orifice 28b in the direction of the drain piping (see the direction of flow of waste water and waste indicated by the arrows).
- the macerator turbine 28 is activated and then fully plays its role of suctioning and grinding the solid waste from the bowl 12 insofar as it occurs after the bowl 12 has been filled with water and not during the supply of water.
- the turbine of the pump 24 is, in turn, driven in rotation in the opposite direction of the arrow on the figure 2 .
- the reverse rotation of the turbine of the pump 24 does not create suction in the bowl 12 via the pipe connecting the arrival 14 at the output 24b (pump not activated in the second direction of rotation).
- the noise generated by the installation is reduced for example to a noise level of about 60 dB, where the two simultaneous operations generate a noise level close to 70 dB.
- the pump 24 has been configured to reduce the noise level during operation.
- control member 30 also comprises a third control state for putting the motor to a standstill (central position in dashed line on the Figures 4 and 5 ).
- the wheel 32 of the macerator turbine is for example mounted on a ball bearing ratchet allowing only one direction of travel (for example, a freewheel system existing on bicycles).

Description
L'invention est relative à une unité fonctionnelle motorisée pour installation de toilettes et à une installation de toilettes comprenant une telle unité.The invention relates to a motorized functional unit for installing toilets and to a toilet installation comprising such a unit.
On connait des installations de toilettes qui sont embarquées à bord de navires. Une telle installation de toilettes par exemple commercialisée par la société TMC Technology Corp. comprend de manière générale :
- une cuvette de toilettes qui comporte une arrivée d'eau pour amener l'eau dans la cuvette et une évacuation pour évacuer l'eau usée et les déchets solides hors de la cuvette,
- et une unité fonctionnelle motorisée reliée à la cuvette.
- a toilet bowl that has a water inlet to bring water into the bowl and an evacuation to evacuate the wastewater and solid waste out of the bowl,
- and a motorized functional unit connected to the bowl.
L'unité fonctionnelle motorisée comprend :
- un moteur équipé d'un arbre de sortie,
- une pompe auto-amorçante montée sur l'arbre de sortie du moteur et qui est apte à aspirer de l'eau par une entrée (raccordée à une source d'eau telle que l'eau de mer sur un navire) et à refouler l'eau aspirée par une sortie (raccordée à l'arrivée d'eau de la cuvette) pour alimenter la cuvette des toilettes,
- une turbine dilacératrice montée sur l'arbre de sortie du moteur en aval de la pompe et qui est apte à aspirer, par une entrée (raccordée à l'évacuation de la cuvette), de l'eau usée et des déchets solides provenant de la cuvette des toilettes et à évacuer l'eau usée et les déchets dilacérés par une sortie.
- an engine equipped with an output shaft,
- a self-priming pump mounted on the output shaft of the engine and which is able to suck water through an inlet (connected to a source of water such as seawater on a ship) and to repress the water sucked by an outlet (connected to the water inlet of the bowl) to feed the toilet bowl,
- a macerator turbine mounted on the output shaft of the engine downstream of the pump and which is adapted to suck, through an inlet (connected to the evacuation of the bowl), the waste water and solid waste from the toilet bowl and to evacuate the wastewater and garbage dilacerated by an outlet.
Lorsque le moteur est mis en marche, l'arbre de sortie tourne et entraîne en rotation simultanément la pompe et la turbine.When the engine is started, the output shaft rotates and simultaneously drives the pump and the turbine.
Ainsi, l'eau de rinçage est aspirée et refoulée dans la cuvette des toilettes tandis que la turbine dilacératrice aspire en même temps le contenu de la cuvette des toilettes.Thus, the rinsing water is sucked and discharged into the toilet bowl while the turbine macerator sucks at the same time the contents of the toilet bowl.
Le bruit associé au fonctionnement d'une telle installation occasionne une gêne pour les utilisateurs.The noise associated with the operation of such an installation causes discomfort for the users.
Par ailleurs, le débit de rinçage doit être suffisamment élevé pour permettre l'aspiration simultanée par la turbine dilacératrice.In addition, the flushing rate must be high enough to allow simultaneous suction by the blower turbine.
Au vu de ce qui précède il serait donc utile d'améliorer de manière simple le fonctionnement d'une telle installation et, notamment, d'améliorer de manière simple l'unité fonctionnelle qu'elle intègre, que ce soit pour une utilisation à bord d'un navire ou non.In view of the foregoing it would therefore be useful to improve in a simple manner the operation of such a facility and, in particular, to improve in a simple way the functional unit that it integrates, whether for use on board of a ship or not.
On connait du document
La présente invention prévoit ainsi de remédier à au moins un des inconvénients précités en proposant une unité fonctionnelle motorisée pour toilettes, caractérisée en ce qu'elle comprend :
- un moteur,
- une pompe auto-amorçante reliée au moteur et qui est apte à aspirer de l'eau par une entrée et à refouler l'eau aspirée par une sortie, par exemple pour alimenter une cuvette des toilettes, lorsque le moteur tourne dans un premier sens de rotation,
- une turbine dilacératrice reliée au moteur et qui est apte, d'une part, à aspirer, par une entrée, de l'eau usée et des déchets solides, par exemple provenant de la cuvette des toilettes, et à dilacérer les déchets aspirés et, d'autre part, à évacuer l'eau usée et les déchets dilacérés par une sortie lorsque le moteur tourne dans un second sens de rotation opposé au premier sens de rotation,
- au moins un organe de commande du moteur qui, sur actionnement d'un utilisateur, peut prendre au moins deux états de commande possibles, à savoir un premier état dans lequel le moteur est commandé pour tourner dans le premier sens de rotation et un second état dans lequel le moteur est commandé pour tourner dans le second sens de rotation.
- a motor,
- a self-priming pump connected to the engine and which is adapted to suck water through an inlet and to discharge the water sucked by an outlet, for example to feed a toilet bowl, when the engine rotates in a first direction of rotation,
- a macerator turbine connected to the engine and which is able, on the one hand, to suck, through an inlet, wastewater and solid waste, for example from the toilet bowl, and to dilacerate the waste aspired and, on the other hand, to evacuate the waste water and the waste dilacerated by an outlet when the motor rotates in a second direction of rotation opposite to the first direction of rotation,
- at least one motor control member which, when actuated by a user, can take at least two possible control states, namely a first state in which the motor is controlled to rotate in the first direction of rotation and a second state wherein the motor is controlled to rotate in the second direction of rotation.
L'unité fonctionnelle selon l'invention assure ainsi deux fonctions (d'une part, remplissage d'eau avec la pompe dans un premier sens de rotation et, d'autre part, pompage et dilacération des déchets avec la turbine dans un second sens de rotation opposé) qui sont dissociées contrairement à l'art antérieur où les deux fonctions sont réalisées simultanément. La turbine dilacératrice est configurée pour assurer dans un seul sens de rotation (second sens de rotation du moteur) à la fois le pompage ou l'aspiration des eaux usées et des déchets et la dilacération de ces déchets. La turbine dilacératrice comprend ainsi par exemple des organes périphériques montés sur un moyeu central et ces organes assurent à la fois le pompage ou l'aspiration des eaux usées et des déchets et la dilacération de ces déchets (dans le second sens de rotation du moteur). Cet agencement est particulièrement simple et efficace par rapport à un agencement dans lequel le pompage et la dilacération sont exécutés par des organes distincts et éloignés l'un de l'autre. Par ailleurs, chaque fonction est réalisée en utilisant un sens de rotation différent du moteur si bien qu'une seule fonction est exécutée à la fois pour un sens de rotation donné. Le bruit associé au fonctionnement d'une telle unité fonctionnelle est ainsi considérablement réduit. Plus particulièrement, la pompe auto-amorçante et la turbine dilacératrice ont chacune un sens de rotation préféré (opposé l'un de l'autre) dans lequel elles sont chacune actives, c'est-à-dire qu'elles produisent leur plein effet ou effet maximal dans ce sens de rotation. Par contre, dans l'hypothèse où chacune d'elles est amenée à tourner dans le sens opposé à son sens de rotation préféré dit « actif », elle ne produit pas son plein effet dans l'unité fonctionnelle. Ainsi, par exemple, la turbine dilacératrice tournant dans le premier sens de rotation (premier sens de rotation du moteur), ne peut pas ou quasiment pas aspirer de l'eau et ne peut pas ou quasiment pas dilacérer des déchets. Une telle unité fonctionnelle dans laquelle la turbine dilacératrice tournerait dans le premier sens de rotation ne permettrait donc pas d'assurer de manière satisfaisante la fonction d'aspiration d'eaux usées et de déchets et de dilacération desdits déchets. Les déchets seraient imparfaitement dilacérés, voire non dilacérés et cela pourrait conduire à des dysfonctionnements tels qu'un bouchage de conduites....En outre, le découplage des deux fonctions permet d'optimiser le fonctionnement d'une telle unité fonctionnelle et, en particulier, de l'installation de toilettes qui peut l'intégrer. En effet, le remplissage de la cuvette est d'abord effectué (premier sens de rotation du moteur), puis le pompage et la dilacération des déchets solides mélangés à l'eau de remplissage intervient (second sens de rotation du moteur).The functional unit according to the invention thus provides two functions (on the one hand, water filling with the pump in a first direction of rotation and, on the other hand, pumping and splitting waste with the turbine in a second direction opposite rotation) which are dissociated unlike the prior art where the two functions are performed simultaneously. The turbine The macerator is configured to ensure in one direction of rotation (second direction of rotation of the motor) both the pumping or suction of waste water and waste and the mislaying of this waste. The macerator turbine thus comprises for example peripheral members mounted on a central hub and these organs ensure both the pumping or suction of waste water and waste and the mislaying of this waste (in the second direction of rotation of the engine). . This arrangement is particularly simple and effective with respect to an arrangement wherein pumping and tearing are performed by separate members and spaced apart from each other. Furthermore, each function is performed using a different direction of rotation of the motor so that only one function is performed at a time for a given direction of rotation. The noise associated with the operation of such a functional unit is thus considerably reduced. More particularly, the self-priming pump and the macerator turbine each have a preferred direction of rotation (opposite to each other) in which they are each active, that is, they produce their full effect. or maximum effect in this direction of rotation. By cons, in the case where each of them is rotated in the opposite direction to its preferred direction of rotation called "active", it does not produce its full effect in the functional unit. Thus, for example, the turbine blade rotating in the first direction of rotation (first direction of rotation of the motor), can not or almost not suck water and can not or almost not tear waste. Such a functional unit in which the macerator turbine would rotate in the first direction of rotation would therefore not satisfactorily ensure the function of suction of waste water and waste and of dilaceration of said waste. The waste would be imperfectly dilacerated, even undamaged, and this could lead to malfunctions such as clogging of lines. Moreover, the decoupling of the two functions makes it possible to optimize the operation of such a functional unit and, in particular, the installation of toilets that can integrate it. Indeed, the filling of the bowl is first performed (first direction of rotation of the motor), then the pumping and the dilaceration of solid waste mixed with the filling water occurs (second direction of rotation of the engine).
Selon d'autres caractéristiques prises isolément ou en combinaison l'une avec l'autre :
- la pompe auto-amorçante est munie sur une sortie d'un système de clapet anti-retour ; ainsi, quand la pompe est entrainée dans le second sens de rotation, elle est rendue inefficace de par la présence de ce système anti-retour qui l'empêche d'aspirer de l'eau et/ou de l'air en provenance de la cuvette ;
- la pompe auto-amorçante est une pompe à pales déformables ;
- la turbine dilacératrice comprend des pales dilacératrices qui sont configurées pour, dans le second sens de rotation du moteur, aspirer l'eau usée et les déchets solides par son entrée et dilacérer les déchets aspirés; la turbine a une configuration qui la rend ainsi particulièrement inapte à l'aspiration et à la dilacération de déchets à partir de sa sortie lorsque le moteur tourne dans le premier sens de rotation ;
- la turbine dilacératrice munie de ses pales dilacératrices possède un diamètre compris entre 8 et 12 cm, le diamètre étant celui d'un cercle qui tangente le bord périphérique extérieur des pales (dans un plan perpendiculaire à l'axe de la turbine) ; un tel diamètre permet d'assurer une fonction de dilacération satisfaisante ; en effet, si le diamètre est trop grand les déchets ne sont pas suffisamment dilacérés car la vitesse d'écoulement est trop faible et si le diamètre est trop petit on constate la formation d'un trop grand nombre de tourbillons perturbateurs et, en outre, le risque de colmatage de la turbine par des déchets de toutes sortes (cheveux..) est élevé ;
- la sortie de la turbine dilacératrice est disposée tangentiellement à la chambre dans laquelle est logée la turbine dilacératrice pour favoriser l'évacuation de l'eau usée et des déchets dilacérés lorsque le moteur tourne dans le premier sens de rotation ; la configuration de la sortie de la turbine la rend ainsi particulièrement inapte à l'aspiration à partir de sa sortie lorsque le moteur tourne dans le premier sens de rotation ;
- la sortie de la turbine dilacératrice s'étend vers l'extérieur de manière coudée ou courbée afin de rendre difficile l'aspiration d'eau par la sortie lorsque le moteur tourne dans le premier sens de rotation; une telle disposition rendant très difficile l'aspiration d'eau par cette sortie peut par exemple prendre une forme « de coquille d'escargot » ;
- le moteur, la pompe auto-amorçante et la turbine dilacératrice sont disposés dans une configuration rectiligne ;
- la pompe auto-amorçante est disposée entre le moteur et la turbine dilacératrice ;
- le moteur est disposé entre la pompe auto-amorçante et la turbine dilacératrice ; cet agencement est par exemple obtenu par montage de la pompe et de la turbine respectivement aux deux extrémités opposées d'un axe relié au moteur et débouchant de part et d'autre dudit moteur.
- the self-priming pump is provided on an outlet of a non-return valve system; thus, when the pump is driven in the second direction of rotation, it is made ineffective by the presence of this non-return system which prevents it from drawing water and / or air from the bowl;
- the self-priming pump is a pump with deformable blades;
- the macerator turbine comprises macerator blades which are configured for, in the second direction of rotation of the motor, suck the wastewater and solid waste through its inlet and dilacerate the waste aspired; the turbine has a configuration that makes it particularly unsuitable for the suction and the trash of waste from its output when the motor rotates in the first direction of rotation;
- the bladed turbine with its blade blades has a diameter of between 8 and 12 cm, the diameter being that of a circle which tangents the outer peripheral edge of the blades (in a plane perpendicular to the axis of the turbine); such a diameter makes it possible to ensure a satisfactory tearing function; indeed, if the diameter is too large the waste is not sufficiently dilacerated because the flow velocity is too low and if the diameter is too small, there is the formation of too many disturbing vortices and, in addition, the risk of clogging of the turbine by waste of all kinds (hair ..) is high;
- the output of the macerator turbine is arranged tangentially to the chamber in which is housed the macerator turbine to promote the evacuation of wastewater and waste tears when the motor rotates in the first direction of rotation; the configuration of the outlet of the turbine thus makes it particularly unfit for suction from its outlet when the motor rotates in the first direction of rotation;
- the outlet of the turbine blade extends outwardly in a bent or curved manner so as to make it difficult to draw water through the outlet when the motor rotates in the first direction of rotation; such a provision making it very difficult suction of water through this outlet can for example take a form of "snail shell";
- the motor, the self-priming pump and the macerator turbine are arranged in a rectilinear configuration;
- the self-priming pump is disposed between the motor and the blower turbine;
- the motor is arranged between the self-priming pump and the blower turbine; this arrangement is for example obtained by mounting the pump and the turbine respectively at two opposite ends of an axis connected to the motor and opening on either side of said motor.
L'invention a aussi pour objet une Installation de toilettes, caractérisée en ce qu'elle comprend :
- une cuvette de toilettes qui comporte une arrivée d'eau pour amener l'eau de remplissage dans la cuvette et une évacuation pour évacuer l'eau usée et les déchets solides hors de la cuvette,
- une unité fonctionnelle motorisée pour toilettes telle que brièvement exposée ci-dessus et dans laquelle :
- l'entrée de la pompe auto-amorçante est raccordée à une source d'eau de remplissage et la sortie est raccordée à l'arrivée d'eau de la cuvette,
- l'entrée de la turbine dilacératrice est raccordée à l'évacuation de la cuvette.
- a toilet bowl which has a water inlet for supplying the filling water into the bowl and an evacuation for discharging waste water and solid waste out of the bowl,
- a motorized functional unit for toilets as briefly described above and wherein:
- the inlet of the self-priming pump is connected to a source of filling water and the outlet is connected to the water inlet of the bowl,
- the inlet of the macerator turbine is connected to the evacuation of the bowl.
Comme déjà décrit, une telle installation génère moins de bruit qu'auparavant lors de sa mise en oeuvre et son fonctionnement est optimisé.As already described, such an installation generates less noise than before during its implementation and its operation is optimized.
Selon une caractéristique possible, la turbine dilacératrice comprenant des pales dilacératrices qui sont configurées pour, dans le second sens de rotation du moteur, aspirer l'eau usée et les déchets solides par son entrée et dilacérer les déchets aspirés, la turbine possède un diamètre qui est au moins égal au diamètre interne du raccord entre l'entrée de la turbine et l'évacuation de la cuvette, le diamètre étant celui d'un cercle qui tangente le bord périphérique extérieur des pales ; un tel agencement permet de dilacérer les déchets de manière satisfaisante sans colmater ; si le diamètre est trop petit, le risque de colmatage de la turbine par des déchets aspirés est en effet élevé et on constate la formation d'un trop grand nombre de tourbillons perturbateurs ; si le diamètre est trop grand, les déchets ne sont pas suffisamment dilacérés car la vitesse d'écoulement est trop faible.According to one possible characteristic, the blade mill comprising blade blades which are configured for, in the second direction of rotation of the motor, to draw the waste water and the solid waste by its entry and to dilacerate the waste aspired, the turbine has a diameter which is at least equal to the internal diameter of the connection between the inlet of the turbine and the evacuation of the bowl, the diameter being that of a circle which tangents the outer peripheral edge of the blades; such an arrangement allows the waste to be dilactively satisfactory without clogging; if the diameter is too small, the risk of clogging of the turbine by aspired waste is indeed high and there is the formation of too many swirls disruptive; if the diameter is too large, the waste is not sufficiently dilacerated because the flow velocity is too low.
L'invention prévoit l'utilisation de l'unité fonctionnelle motorisée pour toilettes telle que brièvement exposée ci-dessus ou de l'installation de toilettes telle que brièvement exposée ci-dessus à bord d'un engin maritime.The invention provides for the use of the motorized functional toilet unit as briefly described above or the toilet facility as briefly described above onboard a maritime machine.
On notera toutefois que l'unité fonctionnelle ou l'installation de toilettes selon l'invention peut être utilisée à d'autres fins et/ou dans d'autres domaines techniques qu'à bord d'engins maritimes tels que des navires et des sous-marins.However, it should be noted that the functional unit or the installation of toilets according to the invention can be used for other purposes and / or in other technical fields than on board marine vehicles such as ships and -marins.
L'invention a également pour objet un procédé de mise en oeuvre d'une unité fonctionnelle motorisée pour toilettes, caractérisée en ce que l'unité fonctionnelle comprend :
- un moteur,
- une pompe auto-amorçante reliée au moteur et qui est apte à aspirer de l'eau par une entrée et à refouler l'eau aspirée par une sortie, par exemple pour alimenter une cuvette des toilettes, lorsque le moteur tourne dans un premier sens de rotation,
- une turbine dilacératrice reliée au moteur et qui est apte, d'une part, à aspirer, par une entrée, de l'eau usée et des déchets solides, par exemple provenant de la cuvette des toilettes, et à dilacérer les déchets aspirés et, d'autre part, à évacuer l'eau usée et les déchets dilacérés par une sortie lorsque le moteur tourne dans un second sens de rotation opposé au premier sens de rotation,
- commande du moteur dans le premier sens de rotation afin que la pompe auto-amorçante aspire de l'eau par son entrée et la refoule par sa sortie,
- commande du moteur dans le second sens de rotation afin que la turbine dilacératrice aspire par son entrée de l'eau usée et des déchets solides, les dilacère et évacue par sa sortie l'eau usée et les déchets dilacérés.
- a motor,
- a self-priming pump connected to the engine and which is adapted to suck water through an inlet and to discharge the water sucked by an outlet, for example to feed a toilet bowl, when the engine rotates in a first direction of rotation,
- a macerator turbine connected to the engine and which is able, on the one hand, to suck, through an inlet, wastewater and solid waste, for example from the toilet bowl, and to dilacerate the waste aspired and, on the other hand, to evacuate the waste water and the waste dilacerated by an outlet when the motor rotates in a second direction of rotation opposite to the first direction of rotation,
- controlling the motor in the first direction of rotation so that the self-priming pump sucks water through its inlet and delivers it back through its outlet,
- control of the motor in the second direction of rotation so that the macerator turbine sucks wastewater and solid waste through its inlet, dilacers them and evacuates the waste water and the dilacerated waste through its outlet.
Ce procédé procure les mêmes avantages de séparation dans le temps des fonctions principales de l'unité fonctionnelle pour toilettes selon l'invention telle que brièvement exposée ci-dessus.This method provides the same advantages of time separation of the main functions of the toilet functional unit according to the invention as briefly described above.
Selon une caractéristique possible, la sortie de la pompe auto-amorçante est bloquée afin de l'empêcher d'aspirer par la dite sortie. Les caractéristiques possibles exposées plus haut en relation avec l'unité fonctionnelle et/ou l'installation de toilettes la comprenant s'appliquent également au procédé ci-dessus.According to one possible characteristic, the output of the self-priming pump is blocked in order to prevent it from sucking by said outlet. The possible characteristics set out above in connection with the functional unit and / or the installation of toilets comprising it also apply to the above method.

Comme représenté à la
- une cuvette de toilettes 12 qui comporte une arrivée 14 d'eau de remplissage pour amener l'eau de remplissage dans la cuvette et une évacuation 16 pour évacuer l'eau usée et les déchets solides hors de la cuvette,
- une unité fonctionnelle motorisée 20 pour toilettes qui est reliée à la
cuvette 12.
- a
toilet bowl 12 which has aninlet 14 for filling water to bring the filling water into the bowl and anoutlet 16 for discharging the waste water and the solid waste out of the bowl, - a motorized functional unit 20 for toilets which is connected to the
bowl 12.
L'unité fonctionnelle motorisée 20 comprend de manière générale :
- un moteur 22 alimenté par une source d'énergie électrique 23 telle qu'une batterie ;
- une pompe auto-
amorçante 24 reliée à l'arbre de sortie 22a du moteur (illustré en pointillés sur lafigure 1a ), qui est apte à aspirer de l'eau de remplissage par une entrée 24a raccordée à une source d'eau de remplissage 26 (la source 26 est par exemple de l'eau de mer ou un réservoir d'eau douce) et à refouler,par une sortie 24b raccordée à l'arrivée d'eau 14 de la cuvette, l'eau de remplissage qui a été aspirée lorsque le moteur 22 tourne dans un premier sens de rotation ; une turbine dilacératrice 28 également reliée au moteur, qui est apte, d'une part, à aspirer,par une entrée 28a raccordée à l'évacuation 16 de la cuvette 12 par l'intermédiaire d'uneportion de conduit 29, de l'eau usée et des déchets solides (matière fécale...) provenant de la cuvette et à dilacérer lesdits déchets aspirés et, d'autre part, à évacuer,par une sortie 28b raccordée à une tuyauterie d'évacuation, l'eau usée et les déchets dilacérés lorsque le moteur tourne dans un second sens de rotation opposé au premier sens de rotation ;- un organe de commande du moteur 30 qui, sur actionnement d'un utilisateur, peut prendre au moins deux états de commande possibles, à savoir un premier état dans lequel le moteur est commandé pour tourner dans le premier sens de rotation et un second état dans lequel le moteur est commandé pour tourner dans le second sens de rotation.
- a
motor 22 powered by anelectric power source 23 such as a battery; - a self-priming
pump 24 connected to theoutput shaft 22a of the engine (shown in dashed lines on thefigure 1a ), which is able to draw filling water through an inlet 24a connected to a source of filling water 26 (thesource 26 is for example sea water or a fresh water reservoir) and to discharging, by anoutlet 24b connected to thewater inlet 14 of the bowl, the filling water which has been sucked when themotor 22 rotates in a first direction of rotation; - a
macerator turbine 28 also connected to the engine, which is adapted, on the one hand, to suck, through aninlet 28a connected to theoutlet 16 of thebowl 12 via a portion ofconduit 29, the waste water and solid waste (fecal matter ...) from the bowl and to dilacerate said waste aspired and, on the other hand, to discharge, through anoutlet 28b connected to a discharge pipe, the wastewater and garbage garbage when the motor rotates in a second direction of rotation opposite the first direction of rotation; - a control member of the
motor 30 which, when actuated by a user, can take at least two possible control states, namely a first state in which the motor is controlled to rotate in the first direction of rotation and a second state in which the motor is controlled to rotate in the second direction of rotation.
A titre d'exemple, la pompe auto-amorçante 24 est une pompe à pales déformables telle qu'illustrée sur la
Cette pompe 24 comporte un carter auquel sont raccordés une entrée 24a et une sortie 24b d'eau (et des conduites ou portions de conduite pour le raccord à la source 26 et à la cuvette 14 respectivement) et dans lequel est aménagée une chambre 24c. La pompe 24 comporte, logés dans la chambre 24c, un moyeu central 24d à la périphérie duquel sont régulièrement réparties plusieurs pales déformables 24e. La chambre 24c présente sur une partie 24g de sa circonférence une forme oblongue et, sur la partie diamétralement opposée 24h, une forme circulaire. La turbine (moyeu 24d et pales 24e) est montée dans la chambre 24c afin que, lors de la rotation de la turbine, les pales 24e s'écrasent contre la zone 24g de la paroi périphérique interne de la chambre qui est la plus proche des pales, permettant ainsi d'aspirer un volume d'eau provenant de l'entrée 24a entre les pales et de l'évacuer par la sortie 24b. Les pales qui sont en contact avec la zone diamétralement opposée de forme circulaire 24h de la paroi sont relativement faiblement courbées dans la mesure où la hauteur de relevage exigée est relativement faible et où l'on cherche à réduire le frottement et l'usure des pales contre la paroi. Par exemple, les pales sont réalisées dans un caoutchouc nitrile 60 shore afin de conférer des propriétés de souplesse et d'auto-lubrification.This
On notera que la forme oblongue de la zone 24g est peu prononcée afin de réduire le plus possible la génération de bruit et de permettre les deux sens de rotation de la turbine de la pompe.Note that the oblong shape of the zone 24g is not very pronounced in order to minimize the noise generation and to allow both directions of rotation of the pump turbine.
La pompe 24 est équipée à sa sortie 24b (sortie de la chambre 24c) d'un système de clapet anti-retour 24f qui est représenté, à titre d'exemple, par une bille et un siège de clapet.The
Un exemple de turbine dilacératrice 28 est illustré sur la
La turbine comprend une roue de turbine 32 qui comporte une partie centrale 34 et une partie annulaire 36 portant à sa périphérie une pluralité de pales dilacératrices 38. Les pales comportent des arêtes qui sont acérées afin d'être aptes à dilacérer les déchets solides (les arêtes sont plus particulièrement disposées en regard de l'entrée 28a de la turbine). Chaque pale est pliée par rapport à la circonférence de la partie annulaire et s'étend par exemple suivant un angle de l'ordre de 45° par rapport à cette dernière. Plus particulièrement, chaque pale est incurvée et présente une forme globalement hélicoidale. La partie centrale 34 comprend un embout cylindrique 34a ouvert à son extrémité libre et qui entouré d'une collerette 34b également cylindrique.La roue de turbine 32 est montée dans la chambre centrale 40 d'un boitier 42 qui est ouverte sur une face constituant l'entrée 28a de la turbine. Cette face ouverte du boitier est disposée en regard de l'extrémité ouverte de la portion de conduit 29 (raccord entre l'évacuation 16 de la cuvette et l'entrée 28a) de la
Les pales dilacératrices 38 de la turbine sont configurées pour aspirer l'eau usée et les déchets solides par son entrée 28a lorsque le moteur tourne dans le second sens de rotation et pour dilacérer les déchets dans ce même sens de rotation. Cette double fonction est assurée par la seule turbine qui forme une seule et même pièce, contrairement à l'agencement décrit dans le document
La sortie de la turbine est configurée hydrauliquement pour, d'une part, favoriser l'évacuation de l'eau usée et des déchets dilacérés lorsque la roue de turbine tourne dans le sens indiqué par la flèche sur la
Comme représenté sur la
Dans la configuration représentée, la pompe 24 est encadrée par le moteur 22 et la turbine 28. L'entrée 28a de la turbine est ainsi directement raccordée à la portion de conduit 29.In the configuration shown, the
Le diamètre de la turbine munie de ses pales (le diamètre est celui d'un cercle qui tangente le bord périphérique extérieur des pales suivant un plan perpendiculaire à l'axe de la turbine) est au moins égal au diamètre interne de la portion de conduit 29. Ceci permet à la turbine d'assurer de manière satisfaisante la double fonction (pompage et dilacération) en évitant les problèmes de colmatage inhérents à l'agencement décrit dans le document

De plus, l'éventuelle dépression que la rotation de ces pales pourrait générer en aval des pales, en direction de la sortie de la turbine, est atténuée par la configuration courbée du conduit de sortie 42a si bien que la turbine aspire peu ou pas par l'intermédiaire de son orifice de sortie 28b (dans le premier sens de rotation du moteur/ turbine dilacératrice non activée).In addition, the possible depression that the rotation of these blades could generate downstream of the blades, towards the outlet of the turbine, is attenuated by the curved configuration of the

Comme le pompage et le broyage des déchets présents dans la cuvette 12 ne sont pas effectués en même temps que le remplissage de la cuvette, le bruit généré par l'installation est réduit par exemple à un niveau sonore d'environ 60 dB, là où les deux opérations simultanées génèrent un niveau de bruit voisin de 70 dB. Par ailleurs, la pompe 24 a été configurée afin de réduire le niveau de bruit lors de son fonctionnement.Since the pumping and grinding of the waste present in the
